Python Slices - Slice Lists and Strings (Extract Elements from Lists and Strings)

In this tutorial, we will go over how to use python slices (slice lists and strings in python). Think of a slice as something that allows you to take a slice out of a sequence of data such as a string or a list (extract certain elements from these lists and strings). Python slices can be useful for stripping out specific values from lists or extracting a substring. Python slices have some syntax tricks that allow you to start at the beginning without specifying the number and the same goes for the end, reverse a list or string, copy a list or string, and increment (step) a list or string which will skip the specified elements.

If you specify a specific end number, the slice will go up to but not include that element. If you specify a specific start number that element is included.

The python slice function has 3 parameters: slice(start, stop, step).
start - An integer number specifying at which position to start the slicing. Default is 0
end - An integer number specifying at which position to end the slicing
step - An integer number specifying the step of the slicing. Default is 1
